An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the ...
Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.
A guidance system is usually part of a Guidance, navigation and control system, whereas navigation refers to the systems necessary to calculate the current position and orientation based on sensor data like those from compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, etc.
From this work it is recommended to use the Cholesky decomposition method. In addition to aircraft applications, GPS/INS has also been studied for automobile applications such as autonomous navigation, [ 13 ] [ 14 ] vehicle dynamics control, [ 15 ] or sideslip, roll, and tire cornering stiffness estimation.

Unlike other methods of navigation, inertial guidance does not rely on observations of land positions or the stars, radio or radar signals, or any other information from outside the vehicle. Instead, the inertial navigator provides the guidance information using gyroscopes that indicate direction and accelerometers that measure changes in speed ...
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target [1] [2] (in contrast to active radar homing, which ...
The main disadvantage of both SACLOS guidance systems in an anti-tank role is that working on angular differences evaluation, it does not allow any notable separation between guidance system and missile launch post the opposite of manual command to line of sight (MCLOS) ones, thus allowing updated version of such anti-tank weapons (notably AT-3 ...
